The Marathon 3 Electric Filing Machine is very compact and easy to travel with. It is ideal for starters but also very suitable for the more advanced nail technicians. It has a forward and reverse function and can be operated by hand or with the foot pedal. The machine is almost soundless and the vibration is insignificant when operating. The speed is adjustable up to 30.000 rpm. The bits can be stored in the designated holes on top of the filing machine, which enables you to reach them easily. The twistlock handpiece can either be placed in the transparent plastic holder, which you can slide on either side of the drill or it can be placed in the silicon holder.
